The next time your boss accuses you of not doing your fair share at work, just show him this list from WalletHub that proclaims that the Dallas-Fort Worth area has five of the hardest working cities in the United States.

Plano (No.3), Irving (No. 5), Garland (tied for No. 6), Arlington (No. 14) and Dallas (No. 15) all rank in the top 20, with Fort Worth close behind at No. 21. The top two cities are about as far apart as they come: Anchorage, Alaska, and Virginia Beach, Virginia.

To determine the rankings for the 116 most populated U.S. cities, WalletHub weighed seven different factors, including average workweek hours, commute times, labor force participation rate (i.e., how many people who can work actually do), workers with multiple jobs, volunteer hours per resident, average number of days people don’t get enough sleep in a month and leisure time spent on an average day.

Average workweek hours were weighted most heavily, followed by labor force participation rate. So we work too many hours, which leaves us little time for leisure and causes us to lose sleep.

When asked why Americans worked so hard, WalletHub’s panel of experts listed myriad reasons, from good old-fashioned work ethic and fear of ending up destitute to chasing the American dream. Ariana Levinson, associate professor of law at Louis D. Brandeis School of Law, University of Louisville, points to U.S. laws — or lack thereof — regarding the workplace and the fact that many U.S. companies don’t offer paid vacation at all, let alone the three weeks that Europeans tend to get.

Other ranking Texas cities include Houston at No. 20, Austin at No. 23 and Corpus Christi at No. 26.
